4Causes and Risk Factors for Morning Sickness
It is still not fully clear what exactly causes morning sickness. However, scientists suggest some possible theories. An increase in the levels of some pregnancy hormones, such as estrogen and human chorionic gonadotropin, may lead to vomiting and nausea symptoms. Other potential factors may play a part as well, such as:
– A family history of severe vomiting during pregnancy
– Psychological changes
– Genetics
– Slower gastric emptying
– A history of motion sickness or migraine
– Pregnancy with a female baby
– A history of severe sickness in previous pregnancies
If you are worried about any of these risk factors, make sure to talk with your doctor to get the best advice. [6]
Medications for Morning Sickness
Some medications can help manage the symptoms of morning sickness. These include Unisom Nighttime Sleep Aid (a combination of doxylamine and vitamin B6), emetrol, reflux medications, vitamin B6, or doxylamine-pyridoxine. During the first trimester, the embryo is especially prone to certain substances that would lead to birth defects. Thus, your doctor may avoid prescribing some medications, such as antihistamines, antispasmodics, and antiemetics. [7]
